YBe it known that l, HENRY RonRDAN'rZ, a citizen ol the linited States, residing at Bul"- lalo, in the county ol'V Erie and State of New York, have invented new and useful lmprovements in Guards for Scart-Pins, &c., olE which the following is a specification.

This invention relates to the guards or rctainers employed for preventing loss or withdrawal of garment-pins ot' various` kinds, such as scarf-pins and hat-pins.

The object olE my invention is the provision et' a neat, simple, and reliable guard ot this kind which can be readily fastened and released and which can be mamilactured at small cost.

ln the accompanying drawings, Figure 1 is a longitudinal section of the detached guard on an exaggerated scale. Fig, 2 is a similar view showing the device applied to a pin. Fig. 3 is a liront elevation of the guard applied to a pin. Figs. 4 and 5 are transverse sections in lines 4 1 and 5 5, Fig. 2.

Similar letters of reference indicate corresponding parts throughout the several views.

A indicates a sleeve forming the body of the guard and adapted to be passed over the lower portion of the pin B.

O is a wedge arranged lengthwise in the lower portion of the sleeve A and serving to clamp the pin within the latter, thereby securely fastening the sleeve to the pin and preventing the pin from being lost or forcibly withdrawn from a scart' or other article without detection by the wearer. The wedge is preferably cylindrical and provided in one side with a longitudinal groove or depression (Z, which receives the pin and which gradually increases in depth toward the inner or front end of the wedge, so that the pin is clamped against the opposing wall of the sleeve A upon lforcing the wedge into the same, as shown in Figs. 2, 4, and 5. In order to provide a large and elfective bearing-surlacc for the wedge against the interior ot' the sleeve, the lower portion of the latteris Ilared toward its lower or rear end, as shown at (l. By this construction the wedge when tightened has an extensive bearing both against the sleeve and the pin and reliably clamps the sleeve upon the pin.

The lower or outer end d/ of the wedge is preferably bent laterally, as shown, for liorming a guard lor the point ol the pin and preventing injury to the wearer's lingers in applying and removing the guard-sleeve A. The angular end il is arranged on the same side olY the wedge as the groove (l. This augular end also lorms a convenient means for seizing the wedge in tightening and loosening it. The l'ront or upper portion A of this sleeve is enlarged to form an internal shoulder e, and the wedge C extends above this shoulder and is provided at its upper end with a stop lip or [lange f, adapted to encounter said shoulder `for preventing complete withdrawal and loss ol the wedge.

Before applying my improved guard to a scarf-pin or the like the wedge is withdrawn to its limit, as shown in Fig. 1. A'lter passing the guard-sleeve A over the pin the wedge is forced into the sleeve `lor clamping the latter upon the pin, this being most conveniently and effectively done by turning the wedge and at the same time Vforcing it farther into the sleeve. To 'facilitate this operation, the sleeve is provided with one or more knurled beads g. In order to release the guard, the wedge is simply turned in the sleeve and at the same time withdrawn, when the wedge will be loosened and permit the guard to be stripped Vfrom the pin.

The enlarged portion A of the guardsleeve forms a hood which incleses the flanged inner end of the wedge, thus improving the appearance of the device. This hood or cxtension may be short or long, as desired. lVhen the device is designed to be applied to diflierent kinds of pins varying more or less in diameter, the wedge when tightened will extend a greater or less distance above the `flaring portion of the guard-sleeve, and in that case it is necessary to make the hood A longer than in a device constructed to receive pins varying but slightly in diameter.

As the device consists ol" but two parts, it can be produced at a low cost.

I claim as my invention- 1, A pin-guard, comprising a sleeve, and a wedge movable lengthwise in the sleeve and provided with a longitudinal pin-groove a portion of which is shallower than the pin IOO adapted to lie in the groove, whereby the pin is clamped between the bottom of said groove and the opposing wall of the sleeve when the wedge is tightened, substantially as set forth.

2. A pin-guard, comprising a sleeve adapted to surround a pin and provided with a flaring bore, and a clamping-wedge arranged in said sleeve and having a longitudinal pingroove which increases in depth toward the front end of the wedge, substantially asset forth.

3. A pin-guard, comprising a sleeve having an internal shoulder, and a wedge Inovable lengthwise in the sleeve and provided at its inner end with a stop lip or liange arranged to encounter said shoulder, substantially as set forth.

4. A pin-guard, comprising a sleeve adapt- HENRY ROHRDANTZ.
